HOT-Al R RADIATO R.

a SPECIFICATION forming part of Letters Patent No. 608,360, dated August 2, 1898.

Application filed February 11,1898. Serial No. 669,891 (No modeh) tracted and whereby air will be circulated and heated.

It further consists of novel details of construction, all as will be hereinafter set forth.

Figures 1 and 2 represent Vertical sectional views of my hot-air radiator on lines at 00, Fig. 2, and y y, Fig. 1, respectively. Fig. 3 represents a plan View of the upper headers employed. Fig. 4 represents a side elevation of the upper portion of the radiator, also embodying my invention. Fig. 5 represents a plan View of the lower flue-box or header.

Similar letters of reference indicate corresponding parts in the figures.

Referring to the drawings, A designates a hot-air radiator having a lower header B, which is continuous and preferably circular, forming a substantially central opening R. The header B is suitably supported in the present instance by the legs 0 and has openings therein, and the collars E, to which are fitted the pipes F, G, H, and J.

Supported on the pipes F and G is an upper header which consists in part of the lower chamber K, whichis provided with openings L and M, registering with said pipes F and G, and suitable collars for connecting said pipes with said header, the latter being also provided with an opening P and a collar Q, to which is fitted a smoke-pipe S, which passes through the opening R and leads to a suitable heat-supply and forms the air-space T between the same and the header B.

U designates the upper chamber of the up-' per header, which is preferably placed at an angle to the lower chamber K,which has openings V, registering with the pipes H and J,

and collars for connection with said pipes,

and having an opening W, registering with a ,of'pipes common to said lower header, and to smoke-pipe Z, for carrying away the products of combustion.

A damper A is situated in the lower chamber K, which has a rod B for operating the same, said damper controlling an opening in the wall of said chamber K, so that a connection between the two chambers K and U may be made, if necessary.

The operation is as follows: When it is desired to utilize as much heat as possible, the damper A is closed and the heat and prod nets of combustion pass up the pipe S into the lower chamber K, (see Fig. 1,) and thence into the pipes F and G, which communicate 6 5 therewith, out of said pipes into the lower header B, and thence into the pipes H and J (see Fig. 2) and into the upper chamberUof the upperheader, from which they pass into the pipe Z and discharge at any desired point. 7:5 It will thus be seen that all the pipes and: headers, as well as the chambers in the latter, are heated, and the heat is directed through a considerable space, and the aircirculates through the space T and is also heate If it is not desired to heat the radiator by opening the damper A, the heat willpass up the pipe S and directly to the pipe Z.

It will be evident that various forms and conductions may be used without departing from the spirit of my invention, and I do not therefore desire to be'li-inited to the exact form as herein shown and described, but may make such changes as come within the scope of my'inventi on.

" Having thus described myinvention, what I claim as new, and desire to secure by Letters Patent, is

1. In a hot air radiator, a lower header having a substantially central opening therethrough,;an upper header consisting of upper and lower chambers, arranged at an angle to each/other, a pipe extending through the opening in said lower header but spaced from the sides of said opening, thereby providing 5 V a passage for the ingress of air, said pipe communicating with the lower chamber of said upper header, a damper located between the chambers of saidupper header, and a series [00 the upper and lower chambers of said upper header.

2. In a hot-air radiator, a lower header, an upper header consisting of upper and lower chambers, arranged at an angle to each other, means for causing the products of combustion to pass over said lower chamber prior to their exit from said upper chamber, a damper located between the chambers of said upper header, a substantially central opening in said lower header, a pipe passing through said opening and leading to the lower chamber of said upper header, said pipe being spaced from the sides of said opening for permitting the ingress of air, which latter flows upper chamber of said upper header, the lat- 2o ter having an outlet-flue leading therefrom.
